'We currently don't have enough empty land to construct a full bpt worth of buildings. Unless we are building cs, we should acquire more land from exploring or attacking before constructing additional buildings."

"full bpt worth of buildings" could use a rewording. The tips seem geared to newbies so in addition to rewording the bpt part, cs maybe could be changed to Construction Sites for consistency since acronyms and abbreviations are not used elsewhere.

Also in the "Luck" bonus description it says "a greater chance of successfully attacking when oversending". Should that not be undersending?

Use this page to send multiple FA packages to one of your countries. The countries do not need to be allied, but all of the other FA restrictions apply. In additiona, every country you select will send the maximum amount of every good you select. For finer control, you must login to the FA page of each country.

I got this message when sending FA: "You sent the following goods to XXXX XXX: 133222346 Money."

It seems a really inelegant way to phrase the amount sent. I guess I can get avoiding the American-centric way of calling it $133222346, but I would think being able to include commas would make it much more readable.
